The rated current as listed is either the saturation current or the heating current depending on which value is lower833 Trise = Coreloss (mW) + DCRloss (mW) (C) 2. The saturation current is the current which causes the 7.05 inductance to drop by 10% at the stated ambient temperatures 1.63 2.17 Coreloss = 1.86E-12 * (Freq (kHz)) * (Kc * Vsec) (mW) (-40C, 25C and 125C). This current is determined by placing the component in the specified ambient environment and apply- 2 DCRloss = Irms * DCR(m) (mW) ing a short duration pulse current (to eliminate self-heating effects) to the component. 2 2 Irms = IDC + dI (Arms) 12 3. The heating current is the DC current which causes the Freq (kHz) = switching frequency (kHz) temperature of the part to increase by approximately 45C. This Vsec = L (H) * dI or V * D * 1000/Freq (kHz) current is determined by mounting the component on a PCB dI = pk pk ripple current across the component (A) with .25 wide, 3 oz. equivalent copper traces, and applying the V = Voltage across the component (V) current to the device for 30 minutes with no forced air cooling. D = Duty cycle 4. In high volt*time applications, additional heating in the 6. TheN suffix indicates an RoHS-compliant part number. Non- component can occur due to losses in the inductor which may NL suffixed parts are not necessarily RoHS compliant, but are neccessitate derating the current in order to limit the electrically and mechanically equivalent to NL versions. If a part temperature rise of the component. In order to determine number does not have theN suffix, but an RoHS compliant the approximate total losses (or temperature rise) for a given version is required, please contact Pulse for availability. application both copper losses and core losses should be taken into account. 7. The temperature of the component (ambient plus temperature rise) must be within the stated operating temperature range. 5. Optional Tape & Reel packaging can be ordered by adding a suffix to the part number (i.e. PD0120.102 becomes PD0120.102T). Pulse complies to industry standard tape and reel specification EIA481.
